> There is a memory leak with the default eviction strategy. It's a leak in org.infinispan.commons.util.concurrent.jdk8backported.BoundedEquivalentConcurrentHashMapV8 with LIRS eviction strategy.
> There are cache entries in org.infinispan.container.DefaultDataContainer.entries and its size are bigger than cache size after eviction occurred.
> DefaultDataContainer.entries retain keys and values for evicted entries in the cache.
> After full GC, DefaultDataContainer.entries size wasn't changed.
> The following minimum reproducer exhibits a leak. Eviction is supposed to suppress OOME.
